VPS With Strong DDoS Protection for Real-Time Apps

[Dromondgovern]

I need a VPS with enterprise-grade L3/L4 protection, ideally with multi-layer filtering.
Specs: 2+ cores, 4+ GB RAM, NVMe. Latency-sensitive workload, so routing stability matters.
Locations in DE, NL, USA, or CA preferred. Can I rely on Hostingsource.com vps hosting solutions? Other options please?

What are the security measures and server backup protocols?
